Mikawa Nagura are Tuff stones, a type of igneous rock formed from lithified volcanic ash. Mined in Aichi prefecture starting 700 years ago, they have been used in traditional Japanese sword polishing progressions. The mine has been closed since the 1970s.

We receive the stones from the wholesaler with rough chisel marks on both sides, and flatten them in our workshop. Although we have made a good effort to provide a flat surface for usage, we strongly recommend end users flatten the sharpening surface once more with a diamond plate.

This particular stone is more friable than average, and is a light yellow colour. There are also black spots and small su at the top of the stone. We have not noticed the release of any gritty particles in use, but the price has nevertheless been reduced to 1.12HKD/g as a result of the aesthetics.
